Objective. After discussing the factors damaging hydrogen peroxide low-temperature plasma sterile packaging bags (hereinafter referred to as Tyvek packaging bags), the damage rate of Tyvek packaging bags is lowered through the control of link quality, so as to guarantee the quality of sterile packaging bags and the safety of patients. Methods. Design questionnaire and registration form by investigating 8606 instrument packaging bags sterilized by hydrogen peroxide low-temperature plasma from January 2019 to December 2019, the controllable factors damaging Tyvek packaging bags are analyzed from four aspects: instrument packaging, sterilization, transfer, and storage. By taking targeted interventions on 8155 instrument packaging bags sterilized from January 2020 to December 2020, the intervention effects of the key links and the damage rate are evaluated. Results. The main factors damaging Tyvek packaging bags mainly include improper transfer, storage, and management of instrument packing bags; improper use of instrument boxes; improper loading and uploading operations of sterilization; and the wrong size of packaging bags. For these factors, related intervention measures shall be adopted to control the link quality so as to lower the damage rate from 3.54% in the control group to 0.20% in the experimental group. The differences in damage rate are of statistical significance ( P < 0.01 ). Conclusion. Tyvek packaging bags are influenced by controllable factors. Through reasonable link control and standard operations, the sterile packaging bags can be kept sterile from the end of sterilization to the usage by patients, which guarantees the safety of patients and is worthy of reference.
目的:研究MRI、CT、X射线三种影像学方法在多发性骨髓瘤(MM)诊断中的应用价值以及影像学表现.方法:选取本院2020年5月～2023年3月收诊的多发性骨髓瘤患者98例为对象,均进行MRI、CT和X射线检查,收集整理三种影像学方法单一应用、联合应用对多发性骨髓瘤的诊断准确率以及三种影像学方法的征象检出率.结果:三种影像学方法对MM的诊断准确率中,X射线最低,显著低于MRI和CT的诊断准确率(P<0.05);而MRI与CT的诊断准确率差异不显著(P>0.05);MRI+CT+X射线的诊断准确率显著高于三种影像学方法单用的诊断准确率(P<0.05);在多发性骨髓瘤的影像学表现中,MRI以椎体部位的骨质破坏检出率最高,多为局灶性或弥漫性的破坏;CT多为溶骨性的骨质破坏,以脊柱和骨盆的骨质破坏检出率较高;X射线多为骨质疏松和穿凿样改变,以头颅的骨质破坏检出率较高.结论:影像学方法在多发性骨髓瘤诊断中应用价值高,适当联合MRI、CT、X射线检查能提高诊断准确率,指导临床治疗.

目的:评估2种镍钛器械行一次性根管治疗期间急发症发生情况.方法:选择2020年5月～2021年12月本院行一次性根管治疗的110例患者作为研究对象.基于SPSS22.0软件生成的随机序列均分为对照组与观察组,每组各55例;对照组给予WaveOne器械根管预备,观察组给予Mtwo器械根管预备;评估比较两组治疗后不同时段(2d与7d)疼痛程度、急发症情况.结果:治疗后2d,观察组VAS疼痛评分(2.41±1.02)分低于对照组的(3.35±1.11)分,P＜0.001;且该组急发症发生率(5.45%)低于对照组(20.00%),P＜0.05.结论:2种常用镍钛器械中Mtwo器械效果更优异,相较于WaveOne器械疼痛程度更轻,急发症发生率更低.
目的:探讨胎儿超声心动图在胎儿先天性心脏病中的诊断应用效果及可行性.方法:选择2021年1月～2021年12月产前系统超声检查孕妇1524例作为对象,所有孕妇均给予常规彩色多普勒超声检查与胎儿超声心动图检查,以胎儿引产病理解剖及随访结果作为"金标准",分析对比常规彩色多普勒超声检查与胎儿超声心动图及二者联合检查在胎儿先天性心脏病中的检出率及先天性心脏病类型;计算不同超声检查方法在胎儿先天性心脏病中的诊断效能.结果:1524例孕妇最终检出106例胎儿先天性心脏病,确诊率为6.96%.排在前三位的分别为室间隔缺损、法洛四联症、右位主动脉弓;彩色多普勒超声联合胎儿超声心动图检出胎儿先天性心脏病阳性102例,检出准确度为99.34%、诊断灵敏度为93.40%、特异度为99.79%、阳性预测值为97.06%、阴性预测值为99.51%;常规彩色多普勒超声检查联合胎儿超声心动图诊断灵敏度及阳性预测值高于单一超声检查(P＜0.05).结论:常规彩色多普勒超声检查与胎儿超声心动图用于胎儿先天性心脏病中能获得较高检出率,且二者联合检查能提高诊断的灵敏度与阳性预测值,且超声诊断具有无创性,能为临床诊疗提供参考依据.
